Sharon and Dave were tallying the number of shooting stars they observed one night. By 10:00 pm they had counted 12 shooting stars. By 1:00 am, they had counted 24. Write a linear equation to model the number of shooting stars (y) according to the number of hours (x). (Let 10:00 pm be represented by x=0)

Which expression is equivalent to? assume x > 0 and y > 0.

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
